Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional water pumps for electronic component cooling systems suffer from low thermal exchange efficiency and motor overload due to inefficient fluid circulation and turbulence, leading to suboptimal heat transfer and potential motor overload.
Innovation Solution
A water pump design with separate inlet and outlet chambers and impellers positioned above the thermal exchange base, allowing simultaneous push and suction actions to minimize turbulence and enhance fluid velocity, while a base cover isolates chambers to prevent thermal energy mixing and improve efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single impeller is used to push working fluid through the thermal exchange base, then the structure is simple, but thermal exchange efficiency is low due to turbulence flow and inefficient circulation
Solution Approach 1:
The pump chamber is divided into a first chamber and a second chamber, with separate first and second impellers in each chamber. This segmentation allows independent control of push and suction actions, eliminating turbulence flow and improving thermal exchange efficiency without excessive structural complexity
Solution Approach 2:
The patent combines push action and suction action into a single integrated pump structure with two chambers working simultaneously. This merging achieves efficient circulation while maintaining structural compactness
2Device complexity
If the thermal exchange chamber is separated from the pump chamber with a passage, then the structure is modular, but working fluid becomes congested causing low thermal exchange efficiency and motor overload
Solution Approach 1:
The pump chamber is segmented into two chambers with separate impellers that directly act on the thermal exchange base. This eliminates congested passages and reduces motor load while maintaining modular benefits
Solution Approach 2:
The dual impeller configuration enables continuous push and suction actions without interruption or congestion, ensuring smooth fluid flow and preventing motor overload
3Ease of operation
If impellers are positioned away from the thermal exchange base, then the chambers are easily accessible, but fluid velocity decreases and residual fluid remains on the base
Solution Approach 1:
The impellers are positioned in the vertical dimension directly above the thermal exchange base channels, allowing them to act directly on the fluid without horizontal distance loss. This maximizes fluid velocity while maintaining chamber accessibility
4Device complexity
If inlet and outlet chambers are not isolated, then the structure is simpler, but thermal energy mixing occurs reducing thermal exchange efficiency
Solution Approach 1:
The pump chamber is segmented into inlet and outlet chambers separated by a partition, preventing thermal energy mixing while maintaining structural simplicity. This segmentation directly improves thermal exchange efficiency
